Abstract	BOCK, A. L. Weigh in motion of road loads and their impact in pavement performance of the brazilian Asphalt Tematic Network. 2016. Thesis (Doctor Degree in Civil Engineering) – PostGraduation Program of Civil Engineering, Federal University os Rio Grande do Sul, UFRGS, Brazil, Porto Alegre. In recent decades the Brazilian road pavements have had their performance reduced due to a number of factors, not only the increasing volume of heavy vehicles and increased transport capacity, but mainly the flow with loads above the established legal limits, setting a critical situation for the durability of the designed structure. Alongside the necessary investment, it is also important to the development of more rational methods of pavement design, considering the specificities of the materials used and taking into account the climatic conditions and a complete and detailed characterization of the traffic. In this context, the research was developed to attain two main objectives: the construction monitoring and systematic assessment of performance of two test sections built in BR-448/RS highway and the continuity of assesment of two others previously built in BR-290/RS, between Osório and Porto Alegre (known as Freeway). These activities are part of the "Integrated Project Theme Technology Network Petrobras Asphalt/ANP", a nationwide project aimed at developing a new Brazilian method for pavement design. The second objective was to conduct a comprehensive monitoring loads study on the Freeway, by installing and carrying on an unprecedented operation of a dynamic weighting equipment of high speed (High speed weigh-in-Motion HS-WIM) to determine the loads spectrum and subsequent analysis of the influence on pavement performance. Both studies made possible to determine the loads spectrum, average loads and levels of overloads practiced on that highway, to estimate how these loads affect the pavement performance and to compare these data with the trends observed through the systematic assessment of the analyzed sections. This work aims to contribute to improvements in road and traffic engineering, by introducing new monitoring technologies, monitoring the transported cargo and contributing to the development of a new design method of flexible pavements, a major goal of the Thematic Network of Asphalt, to be achieved through experimental data collection in test sections, the development of performance models and their subsequent insertion in the calibration models.
